This draft specifies CEQMM, a Complete and Efficient Quality of
Service (QoS) Model for MANETs which combines the positive aspects
of both IntServ and DiffServ. It uses a hybrid per-flow and per-class
provisioning scheme. In such a scheme, traffic of highest priority is
given per-flow provisioning while other priority classes are given
per-class provisioning. To offer this scheme and to ensure that
certain packets receive higher priority transmission than other
packets, priority classifier, active queue management and packet
scheduler are integrated. CEQMM applies the QOLSR protocol to support
multiple-metric routing criteria and to respond quickly when changes
in topology and/or QoS conditions are detected. Once a path is chosen
for one QoS flow, CEQMM performs call admission control (CAC) at each
intermediate node. For only QoS flows of highest priority, a node can
precede to soft and later hard bandwidth reservation on links during
the CAC process. CEQMM implements congestion avoidance mechanisms to
prevent a network from entering the congested state. However, in
MANETs, network congestion can still occur frequently under mobility.
In order to prevent performance degradation due to mobility-triggered
congestion, CEQMM uses congestion control scheme based on: (i) rated
control of best-effort traffic, (ii) path selection for best-effort
traffic, (iii) next hop maintaining for each QoS class (except the
high-priority class), (iv) active queue management and (v) backoff
timer method.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
